Hello,
I hope I could get some help. I have been trying for a while to perform the
following task.
I have a subgroup called "infrastructure" and I would like to create a page
template that goes through all devices in the subgroup and returns me the
values of the following datapoints:
- sum of ssCpuRawSystem + ssCpuRawUser + ssCpuRawWait
- memAvailReal
- ifInOctets of {device}/os/interfaces/eth0
Here is the code I use:
Code:
<tal:block tal:define="devices python:here.getDevices();">
<tal:block tal:repeat="device devices">
<span tal:define="memReal
python:device.getRRDValue('memAvailReal_memAvailReal');">
<span tal:content="device/id">Device ID</span>
<span tal:content="memReal">MemReal</span>
</span>
</tal:block>
</tal:block>
I use "here.getDevices()" to get the list of all devices in the subgroup.
When I call getRRDValue for memAvailReal on each device, nothing is returned,
whereas if I call getRRDValue for a datapoint that I have created (ex: time),
it will return a value. I have tried to use getRRDValue with REST and it
returns a value for memAvailReal on each device of the subgroup.
Concerning the sum, I know I can sum integers like this "python:1+2+3"
but it seems I can not sum like this
"python:device.getRRDValue('ssCpuRawSystem')+device.getRRDValue('ssCpuRawUser')+device.getRRDValue('ssCpuRawWait')"
Is there also a way to call getRRDValue on "{device}/os/interfaces/eth0" ?
Thank you again.
